O high concentration of enzyme
Answer:
Low temperature
Explanation:
because.
Have a great day!!!
The factor that can decrease the rate of a chemical reaction is a low temperature.
What is chemical reaction?A chemical reaction is the chemical transformation of one set of chemical substances into another.
A low temperature is one factor that can slow down a chemical reaction. A chemical reaction is defined as a process that transforms one set of chemical substances into another.
The rate of a chemical reaction is a measure of how quickly the reaction takes place.
A low temperature can slow down a chemical reaction by lowering the kinetic energy of the reacting molecules.
This means the molecules move slower and are less likely to collide with enough energy to break bonds and form new ones. As a result, the reaction rate slows down.
Thus, the answer is low temperature.

Why is it an important property for water to be less dense as a solid?
Answer:
Water has a unique density. It is less dense as a solid than it is as a liquid, which is why ice floats on top of liquid water.
Explanation:
Answer: Water’s lower density in its solid form is due to the way hydrogen bonds are oriented as it freezes: the water molecules are pushed farther apart compared to liquid water. With most other liquids, solidification when the temperature drops includes the lowering of kinetic energy between molecules, allowing them to pack even more tightly than in liquid form and giving the solid a greater density than the liquid.
The low density of ice, an anomaly, causes it to float at the surface of liquid water, such as an iceberg or the ice cubes in a glass of water. In lakes and ponds, ice forms on the surface of the water creating an insulating barrier that protects the animals and plant life in the pond from freezing. Without this layer of insulating ice, plants and animals living in the pond would freeze in the solid block of ice and could not survive. The detrimental effect of freezing on living organisms is caused by the expansion of ice relative to liquid water. The ice crystals that form upon freezing rupture the delicate membranes essential for the function of living cells, irreversibly damaging them. Cells can only survive freezing if the water in them is temporarily replaced by another liquid like glycerol.
what will happen to the concentrations of ATP,NADPH, and sugar when you add paraquat
Answer:
Increase ATP
Decrease NADPH
Decrease Sugar
Concentrations of ATP, NADPH, and sugar decreases when we apply paraquat on the plants.
The concentrations of ATP,NADPH, and sugar decreases when you add paraquat because paraquat is a toxic chemical which blocks the activity of respiration in plants leading death of those plants. Paraquat inhibits the ATPase activity which is responsible for the production of ATP.
So due to no cellular respiration no ATP is produced. Paraquat (PQ) also inhibit photosynthesis so no glucose as well as NADPH is produced so we can conclude that concentrations of ATP, NADPH, and sugar decreases when we apply paraquat on the plants.

The condition of ketoacidosis is Select one: a. a potentially fatal buildup of acetoacetate or 3-hydroxybutyrate lowering blood pH. b. due to a lowered production of ketone bodies than is normal. c. the increase in pH of the cells due to ketone body production. d. only found when anaerobic catabolism of fat occurs.
Answer:
The correct answer is option A ( a potentially fatal buildup of acetoacetate or 3-hydroxybutyrate lowering blood pH.)
Explanation:
Ketoacidosis results in a type of body metabolic state where the urine concentrations are high in ketone bodies, such as acetoacetic acid , 3-hydroxybutyrate. Fatty acids are converted to ketone bodies, resulting in a very high level of ketone bodies which automatically lowers the blood pH.
Ketoacidosis is of different types, Diabetic ketoacidosis, alcoholic ketoacidosis, starvation ketoacidosis. They are all associated with the accumulation of ketone bodies within the bloodstream. The underlying disease common with ketoacidosis is Diabetes.
Explain how the farms upriver were adding to the high nitrate levels. gizmo
Answer:
Farmers were adding high nitrate levels from many large corn farms along the river. The farmers spray fertilizers that have ammonia and nitrate onto their crops. During the drought, the farmers used extra fertilizer. As rained, the ammonia and nitrate from the fertilizer were washed into the river.
In the pigs produced 10 pounds of feces that contained ammonia and nitrate. The pit is too small to obtain such large amount. When it rained the waste overflowed in to the river.
Explanation:
The drought from the week before and the large rain fall played a large part in the outcome of the annomia and nitrate exposure to water.
The farms upriver were adding to the high nitrate levels. It was because of the excessive use of fertilizers and inadequate waste disposal techniques.
What are agrochemicals?There are chemicals that are used in agriculture. It includes fertilizers, pesticides, nematicides, insecticides, etc.
How does farm upriver add nitrate?The farms upriver used to apply agrochemicals, especially the ones rich in nitrate and urea. During fewer water conditions they used to apply more. That used to remain in the soil and washed down to the river along with the rain.
The farms did not use adequate waste disposal measures and hence the wastes rich in nitrogen were washed down to the river.
Hence, these practices increase nitrate levels in the river.

What is the classification of virus
Answer:
Viruses are classified into 4 groups based on their shape: filamentous, isometric , enveloped, and head and tail.
Many viruses attach to host cells to facilitate penetration of the cell membrane, allowing their replication inside the cell.
The virus core contains the small single- or double-stranded genome that encodes the proteins that the virus cannot get from a host cell.
Explanation:

According to the Baltimore classification system, Viruses are classified into seven classes on the basis of their morphology and function.
What is Virus?A Virus may be defined as a type of microorganism that consists of a nucleic acid molecule in a protein coat and infects cells and may cause disease.
Viruses are classified into seven classes, each of which has its own families of viruses and has differing replication strategies.
Class 1: Double-stranded DNA viruses.
This type of virus usually must enter the host nucleus before it is able to replicate. An Example is Adenoviridae.
Class 2: Single-stranded DNA viruses.
Such types of viruses replicate within the nucleus and pertain highly in vertebrates. An example is Circoviridae.
Class 3: Double-stranded RNA viruses.
Such types of viruses do not depend on host polymerases for replication. An example is Birnaviridae.
Class 4: Single-stranded RNA viruses (positive sense).
Such types of viruses have polycistronic mRNA which is translated into a polyprotein. An example is Flaviviridae.
Class 5: Single-stranded RNA viruses (negative sense).
Such types of viruses must be transcribed by viral polymerases into complementary forms. An example is Filoviridae.
Class 6: Single-stranded RNA viruses (positive sense) that replicate through DNA intermediate.
Such types of viruses use the enzyme reverse transcriptase to convert the positive sense RNA into DNA. An example is Retroviruses.
Class 7: Double-stranded DNA viruses that replicate through a single-stranded RNA intermediate.
Such types of viruses have a double-stranded gapped genome that is subsequently filled into a covalently closed circle that serves as the template for the production of viral mRNA. An example is the Hepatitis B virus.
Therefore, it is well described above.
